BICYCLE-PEDAL.

Specification of Letters Patent.

Patented Jan. 18, 1921.

Application filed April 29, 1920. Serial No. 377,449.

This is accomplished by this invention which is fully descrlbed 1n thefollowlng specification and shown in the accompanying drawing'in Which-Figure 1 is a front elevation of a pedal embodying the invention, andFig. 2 is a longitudinal section through the pedal.

The pedal is supported on an axle which is secured in any desired mannerto the crank 11. This axle has an integral. cone 1O formed thereon nearits inner end and carries a cone 12 which is screwed on the threadedouter end of the axle. A sleeve 13 having an integral bearing cup 14L ateach end, Sl'll'l'OllllClS the axle 10 while balls 15 are placed betweenthese cups and the rones 10 and 12 to form ball bearings.

The threads on the outer end of the axle 10 are interrupted by a smallkey way 10 in which is adapted to slide a finger (not shown) whichextends from the inner edge of the washer 16. Adjustment of the bearingsis made by turning the cone 12 to the desired degree of-tightness whenit is locked by means of the lock nut 17.

A dust cap 18 surrounds the outer end of the axle and bearing and has acounter sunk portion 19 snugly fitting over the outer bearing cup 1lthereby completely inclosing the outer ball bearing, and forming a dustproof cap therefor. i

A. similar dust proof cap is provided for the inner ends of the bearing,a counter sunk portion 21 of which fits snugly over the inner end orinner cup 141-. This dust cap has a round central opening which is givena good running fit on the enlarged portion 22 of shaft 10. By this meansvery little dust is permitted to enter the bearing at the inner end ofthe pedal.

Outwardly extending ears 23 are provided on the (lust cap and similarcars 24 on the dust cap 18, These carry the pedal rolls 25 which extendthrough openings therein and are secured thereto by means of nuts 26,and are shouldered In such a way that when the nuts 26 are drawn downtightly, the dust caps will be drawn firmly over the ends of the tube13. Each of the pedal rods carries a pedal rubber 27 whichmay be of anysuitable I form.

While I have shown and described but a single embodiment of myinvention, it is to be understood that it is capable of manymodifications. Changes, therefore, in the construction and arrangementmay be made wh1ch do not depart from the spirit and scope of theinvention as disclosed in the appended claims in which it is myintention to claim all novelty inherent in the invention as broadly aspossible in view of theprior art..

What I claim as new and desire to secure by Letters Patentis:

1. In combination, an axle, a sleeve surrounding said axle, integralcups formed in the ends of said sleeve, cones on said axle, ballsoperable between said cups and cones, and members removably secured tothe open ends of said sleeve and acting as dust protectors therefor.

2. In combination, an axle, a sleeve surrounding said axle, integralcups formed in the ends of said sleeve, cones on said axle, ballsoperable between said cups and cones, and members removably secured tothe open ends of said sleeve and acting as dust protectors therefor; oneof said members com pletely inclosing the outer end of said sleeve. a

3.111 combination, an axle, a sleeve surrounding said axle, integralcups formed in the ends of said sleeve, cones on said axle, ballsoperable between said cups and cones, and members removably secured tothe open ends of said sleeve and acting as dust protectors therefor; oneof said members having an opening concentric with said axle and closelysurrounding the inner end of the same whereby dust will be excludedtherefrom. l

4. In a bicycle pedal, an axle, a sleeve surrounding said axle, integralcups formed in the ends of said sleeve, cones on said axle, ballsoperable between said cups and cones, a member having a counter sunkportion snuglyfitting over each end of said sleeve, a projection at eachside of each of axle, balls operable betyveen said cups and cones,thecentral portion of said sleeve bemg-smaller than the cups andlthecups being of substantially the same size.

6. In a bicycle pedal, an axle, a sleeve surrounding said axle, integralcups formed in the ends of said sleeve, cones on said axle,

balls operable between said cups and cones,

a member having a counter sunk portion snugly fitting over each end ofsaid sleeve, a projection at each side of each of said members and rodsconnecting said projections, to, secure'the members to the sleeve.

7. In a bicycle pedal, an axle, a sleeve surrounding said axle, integralcups formed in the ends or" said sleeve, cones on said axle, ballsoperable between said cups and cones, a member having a counter sunkportion snugly fitting over each end of said sleeve, a projection ateach side'ot each of said members, rods connectingsaid plojections tosecure the members to the sleeve, and pedal rubbers on sald rods.

S. In a bicycle pedal, an axle, a sleeve surrounding said axle, integralcups formed in the ends of said sleeve, cones on said axlc, ballsoperable between said cups and come, a member having a counter sunkportion snugly fitting over each end of said slecvc, a projection ateach side of each oi said members and pedal rods connecting saidprojections to secure the members to the sleeve.

E). In a bicycle pedal, an axle, a sleeve surrounding said axle, cups inthe ends of said sleeve, cones on said axle. balls operable between saidcups and cones, a member having a counter sunk portion si'iugl fittingover each end of said sleeve. a projection at each side of each of saidmembers and means connecting said projections to secure thc mcmhers tothe sleeve.

10. In a bicycle pedal, an axlc. a sleeve surroundil'ig said axle. cupsin the ends o 1 said sleeve, cones on said axle, ball: open able betweensaid cups and cone a mcnlbcr having a counter sunk portion snuglylitting over each end of said sleeve. a pl'ojwtlon at each side of rachoi said membcis and pedal rods connecting said projections to secure themembers to the sleeve.
